73398854 ÷ 555 
The aim is to understand the frequency of 555 in 73398854.

Going ahead to step 1:
555 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 555

On to step 2:
When dividing 73 by 555, we get 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Append the next digit (3) from the dividend to 73 and continue with: 733 / 555

On to step 3:
733 divided by 555 is 1 with a remainder of 178.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 555 from 733 to get 178.
Bring next digit (9) of the dividend behind the 178 and repeat the process: 1789 / 555

Let's proceed to step 4:
If we divide 1789 by 555, we get 3 and a remainder of 124.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 124 after subtracting 1665 from 1789.
Take the next digit (8) from the dividend and append it to 124, then repeat: 1248 / 555

Step 5:
555 can be fit into 1248 2 times, resulting in a remainder of 138.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
Subtracting 1110 from 1248 leaves us with 138.
Take the next digit (8) from the dividend and append it to 138, then repeat: 1388 / 555

Let's proceed to step 6:
If we divide 1388 by 555, we get 2 and a remainder of 278.
Put 2 as the next digit of the answer. 
Result so far: 1322.0
Subtracting 1110 from 1388 leaves us with 278.
Append the next digit (5) from the dividend to 278 and continue with: 2785 / 555

On to step 7:
555 goes into 2785 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 13225.0
Deduct 2775 from 2785 and we're left with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 555

Moving on to step 8:
104 divided by 555 is 0 with a remainder of 104.
Use 0 as the next digit of our solution. 
Result so far: 132250.0
The remainder is 104 after subtracting 0 from 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 9:
If we divide 1040 by 555, we get 1 and a remainder of 485.
Record the quotient 1 as the next digit in the result. 
Result so far: 132250.1
Subtracting 555 from 1040 leaves us with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

On to step 10:
When dividing 4850 by 555, we get 8 with a remainder of 410.
The next digit of our result is 8. 
Result so far: 132250.18
The remainder is 410 after subtracting 4440 from 4850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 11:
If we divide 4100 by 555, we get 7 and a remainder of 215.
Put 7 as the next digit of the answer. 
Result so far: 132250.187
If we take 3885 away from 4100, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 12:
The number 555 fits into 2150 3 times, leaving a remainder of 485.
The next digit of our result is 3. 
Result so far: 132250.1873
Subtracting 1665 from 2150 leaves us with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Going ahead to step 13:
When dividing 4850 by 555, we get 8 with a remainder of 410.
The next digit of our result is 8. 
Result so far: 132250.18738
The remainder is 410 after subtracting 4440 from 4850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 14:
When dividing 4100 by 555, we get 7 with a remainder of 215.
Put 7 as the next digit of the answer. 
Result so far: 132250.187387
Subtract 3885 from 4100 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 15:
2150 divided by 555 is 3 with a remainder of 485.
Record the quotient 3 as the next digit in the result. 
Result so far: 132250.1873873
If we subtract 1665 from 2150, we get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 16:
If we divide 4850 by 555, we get 8 and a remainder of 410.
Put 8 as the next digit of the answer. 
Result so far: 132250.18738738
Subtract 4440 from 4850 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Our division results in 132250.18738738 with a remaining 4.1e-07.
